Responding to the call of the NHS Nightingale, but at what cost? An auto-ethnography of a volunteer frontline mental health trainer's experiences during the COVID-19 pandemic.

I volunteered to develop and deliver psychological preparedness training - coined 'Psychological PPE' - to over 2300 frontline staff over an 8-week period.
